Submerged combustion can be used advantageously to heat and evaporate saline water and 10 concentrate other corrosive and scale forming liquids. The principal advantage fies in the high evaporation and combustion efficiencies obtained. This work investigates the effects of percentage excess air, totat gas flow rate and submergence on these efficiencies. An increase in percentage excess air tends to improve both the evaporation and combustion efficiencies. An increase in total gas flow rate increases the evaporation efficiency but decreases combustion ei5ciency. Submergence has a slightly negative effect on evaporation efficiency but no significant effect on combustion efficiency, in the short range used in this work.
